was fuel polishing
Thanks to all of you who have given some real good advice. I have always
had a vibration in the fuel line supplying the Westerbeke genny, on the aft
bulkhead in the engine room. This is amplified and is iritating at night.
I think I'll investigate the change to hose, if it is fire proof. It should
be very easy to do.

It is fire resistant to a standard accepted by the USCG. There are fitting
which allow a hose barb to be connected to a flare fitting. I did this, but
don't recall the details.

Or just cut the flare off and put a compression to pipe fitting on it, then
screw on the barb.

NO! NO! NO!
NO COMPRESSION FITTINGS ON OIL LINES!!!!
- They're unacceptable per ABYC. They won't pass muster on a survey.
- They will leak. If not oil out, air in.
- They will come loose.
- The compression nut or the ferrule can crack/break/fail.
- Adapters are asking for trouble. The best connection is the one
you make with a single connection. If you need to get a specialty
adapter but don't have access to one, jury rig it only as long as
needed until a righteous connection can be obtained.

Sorry, but this is not right. If you use a Swagelok compression fitting, it
will last more or less forever, be tough as nails, withstand several thousand
PSI without leaking, and still be easy to disassemble in 20 years. It will
also meet both ABYC and CG regulations.

Then how do you explain sight tubes that are mounted with compression
fittings... already passed survey and never leaked. Matter of fact,
originally the sight tubes were vinyl on hose barbs, and the original
surveyor recommended (required) that I replace them with polycarbonate sight
tubes, necessitating compression fittings. Besides, I'm talking about fuel
lines, not oil lines.

Lucky.
Compression fittings are not good for fuel or oil lines they can fail. They
don't always fail, but too many of them will fail. Fuel lines and oil lines
are points of catastrophic failure. Its OK to use compression fittings on
the ice maker water lines (although some may think failure here is just as
catastrophic :)
Also sight gauges are points of failure. Common sense would suggest they
need to be valved on both ends, have very good fittings and be very hard to
break. This is not the case on the several I saw at the boat shows. I can't
quote government regs, but if your fittings begin to leak or the sight tube
breaks down low you're gonna have a bad day.
Skooch is old (25 years) and has all copper lines for fuel and water. I
carry flare fittings that would make a hardware store proud. I also carry
copper tubing (thick wall like Hatteras used) and the various tools.
Hatteras no longer uses copper, they use hose for fuel and water.

If you were going to re-plumb your water system on your boat would you use
copper. PEX, or CPVC?

I can't say for sure, but I would guess the sight tubes are made up with
a compression ring that consists of a rubber or butyl ring plus a brass
friction ring. Plus they undoubtedly have a shutoff or other service
valve where they connect to the tank to facilitate service. The rubber
ring arrangement is a different animal altogether from the brass ferrule
used in compression fittings. Compression (ferrule) fittings are
notorious for leaking, especially where they're exposed to any vibration
or movement. They do not make a mechanically rigid connection. They may
work, but they're just a poor choice for oil lines when there are far
better alternatives available. BTW, if you're burning diesel, that is
fuel oil. Oil/fuel lines, same difference.
Flaring copper is not at all difficult. I would echo the previous posts
& advise anyone contemplating doing it to get a good flare tool. Ridgid
makes a tool that uses an eccentric flaring ram, it rolls the flare
rather than just pressing it. It also has a release that prevents the
flare from being compressed. Make sure the copper is de-burred before
applying the flare. Murphy says that for every 5 flares you make, you'll
forget to put the nut on at least one!
